IMPROVEME NT IN GATE AND DOOR CLOSING DEVICES.

Specification forming part of Letters Patent No. 218,801, dated August19, 1879 application filed April 28, 1879.

To all whom it may concern:

Be it known that I, WILLIAM HENRY WIL- LIAMS, of Mineola, in the countyof Queens and State of New York, have invented a new and usefulImprovement in Gate and Door Hangings of which the following is aspecification.

My improvements relate. to gate and door hangings wherein the gate isclosed by a weight; and the invention consists in certain novel means,to be hereinafter described, whereby the weight is shifted to change itspurchase and obtain the greatest effect when the gate or door is closed.

I11 the accompanying drawings, Figure 1 is a side elevation of a gatefitted with my improved hangings. Fig. 2 is a top view of the same.

Similar letters of reference indicate corresponding parts.

Ais a gate,hung on post b, and closing against a stop, 6, that is fixedon post (I. The stop 0 is faced with rubber or fitted with a plug ofelastic material, to lessen the concussion.

Upon gate A is a plate, 6, having a projecting lug, e, which plate isattached by a screw and by a bolt, f, to which the chain 9 is held by anadditional nut, f, that permits lengthening or shortening of the chain.The lugv e prevents the chain from getting on the center when the gateis open.

Upon post bis attached a wheel or segment, 71, so as to revolve, andupon the periphery of wheel h the chain g is connected, and the chain issupported intermediately by a grooved friction-wheel, t, that isattached to post b.

The weightlc, for closing the gate, is attached upon the wheel h by aloop, l, in which the weight slides to and from the center of the wheel,and to prevent friction a pulley, m, is applied in the loop I, fromwhich pulley the weight is suspended.

The described parts are to be adjusted so that when the gate is closedthe chain 9 will be partly wound on wheel h and weight k at the outerend of the inclined plane formed by loop I. In this position the weight,being at thereby lessened.

the farthest point from the center, exerts its greatest power to keepthe gate closed and prevent it from being opened by gusts of wind orother causes.

When the gate is being opened by hand, the wheel his turned and looplraised to a horizontal, and finally to an inclined, position, as shownby dotted lines, forming an inclined plane in a direction opposite tothe first position, so that the weight will run toward the wheel andremain there until the gate is again closed. These changes in theposition of the weight can be arranged to occur when the gate is more orless open or closed; and it is to be understood that the weight shouldbe sufficient when at its point of least eifect to close the gate.

I have shown and described the invention in connection with a gate; butit can be applied equally as well to a door.

The advantages of this construction are as follows: The weight may behung on the gatepost, and an extra post is not required. The weight actswith greatest effect to retain the gate closed, and in closing the gateonly the required power for that purpose is exerted, and the concussionagainst the stop will be The gate is more easily opened, and requires nofastening to keep it closed.

Having thus described my invention, 1 claim as new and desire to secureby Letters Patent- 1. In gate and door hangings, the combination, withthe gatechain g and wheel or segment h, of the weight k, fitted to slideto and from the center of h, substantially as and for the purposesspecified.

2. In gate and door hangings, the combination, with the chain-wheel h,of the loop I and loosely-hung weight k, as described and shown, and forthe purposes described.

WILLIAM HENRY WILLIAMS.
